Feeding the birds

I expect you have seen the latest recommendations from the BTO on feeding garden birds.  The new guidance is to stop feeding seeds and peanuts from today to the end of October in the hope of reducing transmission of trichomonosis which has caused declines in populations of chaffinches and greenfinches.

The problem is widespread but seems a bit less up here compared with farther south.  This graph from the BTO Garden BirdWatch shows the reporting rate for greenfinches in the North East.

Compare that with the South East.

These are similar data for chaffinches.

I don't remember ever seeing a finch on the peanut feeder so I think I'll continue with peanuts until they are all used up and see what happens.  That will be a relief to the woodpeckers who will be here with their fledglings in June.

I reckon I only see about one sick finch a year here.  One effect of stopping feeding is that all the finches will disappear so recording of both healthy and sick finches will presumably plummet but I expect the BTO experts have thought about that.  I'll be disappointed not to see the birds but I guess it is all for the greater good.

At the moment I still have lots of siskins, redpolls, bullfinches, greenfinches and chaffinches outside the kitchen window.  They are going to be very disappointed.

My prize visitor, a brambling, was only here for a week before setting off home to Scandinavia about three weeks ago.

Assuming most people comply with the advice it's going to be interesting to see what happens, both here and nationally.  I expect I'll be getting complaints from the local clean-up squad as well.

A siskin spring

After a waxwing winter this is a siskin spring.  I usually see a few of these beautiful finches each year but the last few weeks have been exceptional.  My BTO GardenBirdWatch (GBW) records show the first arrived in the first week of January and numbers built up to 22 by the end of March.  The bird in the photo above had the misfortune to bang his head on the kitchen window but he seemed to make a full recovery.

I have two six port seed feeders, amongst others, but never quite managed a photo with six siskins in one go - there's always a hungry goldfinch spoiling the show.  

I am not the only one to have seen a lot of siskins this year.  The BTO GBW website shows records for the North East.  This is the number of gardens seeing siskins - twice as many as average.

And this is the number per garden, four times higher than average.

My impression that this is a particularly good year for siskins is backed up by this graph showing data from the last 25 years.

I read that the probable explanation for the influx is the persistent wet weather.  Sitka spruce pine cones open in dry weather but remain closed when it is wet so the siskins run short of food and turn to gardens instead.  They mostly live and breed in the conifer forests in Northumberland so I expect they will disappear shortly.

Garden birds

It has been an interesting week for birds on the feeders.  The most exciting sighting was a willow tit.  These photos were taken with the first camera to hand through the window.

I eventually got set up with a better lens with the window open but I have had only a few glimpses since.  This isn't a great photo but it does show the pale wing patch, said previously to be typical of willow tit (but watch the video in the link below).

My BTO Garden BirdWatch records show I have recorded a marsh tit three times in the past 25 years but never a willow tit.  Marsh and willow tits are hard to tell apart and my previous identifications could be wrong but I am grateful to Denise A, Phil A and Phil J for confirming the ID this time.  You can watch a short BTO video on telling marsh tit and willow tit apart here.

There are lots of woodpeckers as well and they tend to monopolise the peanut feeders.  Adults were still feeding fledglings this morning, three weeks after they first appeared.

Another rare summer sighting this week was a male siskin.  I see a few each winter but never before in the summer.  They did breed in the nature reserve only 1km away last year.

And another rare summer bird, a male reed bunting, a regular over the past three weeks.  I expect to see one or two in late spring but never before in the summer.

And previously reed buntings have always been ground feeders here but this one is happy on the seed feeder.

A pair of jays are here every day.  I hope they have a nest nearby and I may see young jays soon.  Jays nested in the garden last year but the nest was wiped out by carrion crows.

Activity on the feeders is frantic at the moment as there are so many young birds.  When it is here the willow tit isn't immediately obvious because there are so many young great tits.

There are almost 30 bird species in the garden each week, mostly regulars but every now and then a surprise.

Out and about in April

It has been a good month for seeing birds in my garden, mostly under the feeders just outside the kitchen window.  The most exciting sighting was a male brambling.  It was only here for a day but I saw it several times throughout the day. By now I expect it is back in Scandinavia or in northern Scotland waiting for a favourable wind for the crossing.

The siskins turned up at the end of March and have been here every day since.  I see at least two females and at least two males but never more than four together.  There may be only four.

Blackcaps arrive from Africa every April and they turned up on time again this year.  There have been two singing males in the copse.  Twice I caught a glimpse of one opposite the front door when I didn't have a camera ready.  The good news is that once when I was waiting with a camera a female turned up, attracted by the song.

I think blackcaps must nest in the garden every year but once the singing stops in May I don't see any sign of them until the youngsters emerge in the summer.  I have never seen an overwintering blackcap but I hear tell of them not far away.  Maybe one winter mine will stay.

Another April visitor every year, but from much closer by, is a male reed bunting.  This one probably came from the nature reserve just north of here.  I expect there isn't much to eat there in April.  Interestingly I have never seen a female here.

Tree sparrows must be well advanced with their nest building.  They can have two or three broods in a season so they need to start early.

I noticed a couple of odd-looking stock doves last month.  This one has scorched-looking primaries so I sent a photo to the BTO and their expert commented that it looks like a genetic or growth problem, which doesn't add much.  The bird seems well.

This one probably has avian pox virus.  It mostly affects tits, sparrows, dunnocks and starlings.  I haven't seen any other affected birds so it probably isn't anything to be concerned about at this stage.

The sparrowhawk still visits regularly but I rarely see it sitting now.  One one occasion it perched on top of the finial on my gazebo after an unsuccessful attack for just long enough for me to get a distant photo.

The dry weather has been tough for birds that rely on earthworms and other soil invertebrates.  Very early one morning I saw this oystercatcher on the golf course opposite the kitchen window, taking advantage of the fact that the greens have been watered.  The oystercatchers arrived to take up their nest sites on the roof of a building across the road in February.  I hope to see one foraging in my garden again in the summer.

The easing of lockdown has meant we are able to travel farther but the cold weather hasn't encouraged expeditions, mainly because the spring is delayed.  In Northamptonshire at the beginning of the month I saw hairy-footed flower bees (Anthophora plumipes), such as this male,

and tawny mining bees (Andrena fulva), such as this female.

At home I saw my first red mason bees (Osmia bicornis).  This male is investigating a hole in the dead sycamore.

This female is sheltering from the cold in the bee house but hasn't started building a nest yet - not here, anyway.  She is adopting a defensive posture, with her middle leg raised, because I have opened the side.

Also in the bee house on the same day was a sleeping queen common wasp (Vespula vulgaris).

At Belsay Hall I saw red-tailed bumblebees (Bombus lapidarius),

whit-tailed bumblebee (Bombus lucorum),

buff-tailed bumblebees (Bombus terrestris),

and common carder bees (Bombus pascuorum).

Also at Belsay I saw blue tits and great tits taking nectar from a very fragrant rhododendron.  I have seen blue tits with pollen on their faces before but have never witnessed this behaviour.

This April may not have been the cruellest month but it was cold and dry.  There was a little bit of rain in the last four days but overall rainfall was very low.  And it was the frostiest April for 60 years.

May isn't starting off much better.  Spring so far is quite late so it will be interesting to see what effect that has on the natural world.
